How do you choose a laboratory flask?

Choose a laboratory flask by matching the flask configuration, nominal capacity, number of necks and required socket or cone sizes. Where an individual page provides height or diameter, those dimensions should also be matched to the apparatus or procurement schedule.

Use the following sequence:

Identify the required flask type.
Select the nominal capacity.
Confirm single-neck or multi-neck construction.
Match each centre, side or angled-neck socket.
Confirm the cone size where listed.
Check height and diameter where supplied.
Request material and operating data not shown online.

A capacity alone is not enough for jointed glassware because several products list the same volume with different socket combinations. Buyers should include the complete product code and configuration in the quotation request.

Which Buchner and Erlenmeyer flask sizes are available?

Buchner Filter Flask JL-LG-1611 is listed in capacities from 100 ml to 1000 ml, with socket sizes expressed as 19/26, 24/29 or 29/32. Standard-Wall Conical Erlenmeyer Flask JL-LG-1612 is listed from 10 ml to 2000 ml with B10 to B34 socket options.

Buchner Filter Flask Options

Capacity	Socket size	Height	Diameter
100 ml	19/26 or 24/29	105 mm	70 mm
250 ml	24/29 or 29/32	140 mm	90 mm
500 ml	24/29 or 29/32	175 mm	110 mm
1000 ml	24/29 or 29/32	220 mm	135 mm

The Erlenmeyer listing includes several socket choices at selected capacities. Material, wall thickness and operating limits are not supplied on the individual page and should be requested where required.

What iodine and Kjeldahl flask options are listed?

Iodine flasks are listed in 250 ml and 500 ml capacities with B24 or B29 socket sizes. Separate iodine-flask stoppers are available in B24 and B29 cone sizes. Kjeldahl Flask JL-LG-1615 lists both socketed flask entries and two separately labelled round-bottom Kjeldahl entries.

Iodine and Kjeldahl Options

Product	Listed capacity or size	Connection
Iodine Flask JL-LG-1613	250 ml, 500 ml	B24 or B29 socket
Iodine Flask Stopper JL-LG-1614	B24, B29	Cone size
Kjeldahl Flask JL-LG-1615	100 ml, 300 ml, 500 ml, 800 ml	B24 socket
Round-Bottom Flask entry on JL-LG-1615	50 ml, 100 ml	B19 listed in cone-size column

Buyers should confirm the intended pairing of iodine flasks and stoppers. The structure and labelling of the Kjeldahl product table also require technical confirmation.

Which Claisen, Vigreux and distillation flasks are available?

Jlab Export lists three compact pear-shaped configurations for Claisen, Claisen-Vigreux and distillation requirements. Their confirmed capacities range from 10 ml to 100 ml, with B10 or B14 socket-and-cone combinations depending on the selected product.

Product	Capacities	Listed connection
Pear-Shaped Flask, Claisen JL-LG-1616	10, 25, 50 and 100 ml	B10/B10 or B14/B14
Pear-Shaped Flask, Claisen, Vigreux JL-LG-1617	25, 50 and 100 ml	B14 socket and B14 cone
Pear-Shaped Flask, Distillation JL-LG-1618	15, 25, 50 and 100 ml	B14 socket and B14 cone

The online pages do not state glass material, column dimensions, side-arm dimensions, overall length or packing quantity. Buyers should request drawings or current technical datasheets where assembly compatibility is important.

How do you select single-neck and multi-neck pear-shaped flasks?

Select a pear-shaped flask by confirming capacity, neck count, neck orientation and every listed socket size. The single-neck range is offered from 5 ml to 100 ml, while the two-neck and three-neck pages each show one listed configuration.

The confirmed configurations include:

Single neck, JL-LG-1619: 5–100 ml; B10, B14, B19 or B24 sockets depending on capacity; heights from 65 mm to 150 mm; diameters from 25 mm to 60 mm.
Two necks, JL-LG-1620: 50 ml; B14 centre socket; B14 side socket; 115 mm height.
Three necks, JL-LG-1621: 25 ml; B10 centre socket; B10 side socket; 115 mm height.

The three-neck listing names one angled and one parallel side neck, but its table provides only one side-socket field. The third-neck connection must therefore be verified.

What Vigreux flask with angled neck is listed?

Pear-Shape Vigreux Flask with Angled Neck JL-LG-1622 is available in 10 ml, 25 ml and 50 ml capacities. All three entries list a B14 main socket, B10 side socket and B14 side cone.

Capacity	Main socket	Side socket	Side cone
10 ml	B14	B10	B14
25 ml	B14	B10	B14
50 ml	B14	B10	B14

The individual listing does not state the Vigreux-section length, indentation count, flask diameter, height, glass material or side-neck angle. These specifications should be requested if they affect the intended apparatus.

Which rotary evaporator flask sizes are available?

Rotary Evaporator Flask JL-LG-1623 is listed from 50 ml to 2000 ml. Capacities from 50 ml to 1000 ml are available with B24 or B29 sockets, while the 2000 ml entry is listed only with a B29 socket.

Available capacities are:

50 ml — B24 or B29
100 ml — B24 or B29
250 ml — B24 or B29
500 ml — B24 or B29
1000 ml — B24 or B29
2000 ml — B29

Buyers should confirm the required socket against the rotary evaporator assembly. Flask shape, wall thickness, overall dimensions and compatibility with a particular evaporator model are not stated and should not be assumed.

Which round-bottom flask configurations are included?

The category includes short-neck round-bottom flasks and two-neck round-bottom flasks with an angled side neck. The short-neck model spans 5 ml to 5000 ml, while the two-neck model spans 100 ml to 2000 ml.

Short-Neck Round-Bottom Flask JL-LG-1624 includes socket sizes from B10 to B55, depending on capacity.

Two-Neck Round-Bottom Flask JL-LG-1625 lists:

Capacity	Centre-neck socket	Angled side-neck socket
100 ml	B24	B14 or B19
250 ml	B24	B14 or B19
500 ml	B24	B14 or B19
1000 ml	B24	B14 or B19
2000 ml	B34	B19

The short-neck table includes a duplicated 250 ml/B29 entry that should be corrected after verification.

Who can procure Jlab Export laboratory flasks?

The category is intended for school, university, TVET, research and industrial procurement. The institution type does not determine the correct product by itself; buyers must select the configuration specified in the laboratory schedule, technical method, apparatus list or BOQ.

Educational buyers may need several capacities or neck arrangements for practical laboratories. Research and industrial buyers may require additional confirmation of material, tolerances, pressure suitability, thermal limits and joint interchangeability.

Jlab Export states that it exports to more than 100 nations across Asia, Africa, Europe, North and South America, and Oceania. This figure should be reconciled with the different figure stated on the live category page before publication.

What should institutional and tender buyers specify?

Institutional and tender buyers should provide the product code, flask configuration, capacity, complete neck and joint details, quantity, destination and documentation requirements. For multi-neck products, every centre, side, angled or parallel neck should be specified separately.

Include:

Product name and JL-LG code
Nominal capacity
Body shape
Number of necks
Centre-neck socket
Side-neck socket
Cone size
Height and diameter, where required
Material requirement
Quantity
Inspection requirements
Packing and marking instructions
Delivery country
Required certificates or datasheets
Tender reference and closing date

Jlab Export lists laboratory glassware among the products offered for institutional and tender supply. Product-specific documents should be requested for the exact quoted code.

Are the listed certifications product-specific?

Product-specific certification is not confirmed on the individual flask pages. The category and About pages contain manufacturer-stated standards and accreditation claims, but these must be verified for current validity, scope and applicability before publishing or using them in procurement.
